Abstract
A component according to an exemplary aspect of the present disclosure includes, among other things, an airfoil that includes a first sidewall and a second sidewall joined together at a leading edge and a trailing edge and extending from a base to a tip. A plenum is defined inside the airfoil. A first cooling cavity merges into the plenum and a second cooling cavity merges into the plenum. A rib extends from at least one of the first sidewall and the second sidewall at least partially into the plenum to separate the first cooling cavity from the second cooling cavity.
Claims19
A component, comprising:
- an airfoil that includes a first sidewall and a second sidewall joined together at a leading edge and a trailing edge and extending radially from a base to a tip;
- a plenum defined inside said airfoil, and said plenum is positioned in said tip;
- a first cooling cavity merging into said plenum;
- a second cooling cavity merging into said plenum;
- and
- a rib that extends from said first sidewall at least partially into said plenum to separate said first cooling cavity from said second cooling cavity, wherein said rib extends radially between opposing sides of said plenum such that said first cooling cavity and said second cooling cavity extend along said first sidewall on opposed sides of said rib, said rib extends transversely between said opposing sides, one of said opposite sides defining a floor and another one of said opposing sides bounded by a wall of said tip, a portion of said rib extends from said first sidewall and terminates prior to said second sidewall, and said first and second cooling cavities have respective first and second outlets into said plenum, said first and second outlets both defined along said floor such that said first and second outlets are spaced apart by said rib.

A gas turbine engine, comprising:
- a component disposed in at least one of a compressor section and a turbine section, wherein said component includes a body that includes a first sidewall and a second sidewall joined together at a leading edge and a trailing edge and extending radially from a base to a tip, said component having an internal cooling scheme comprising:
- a cooling cavity that merges into a plenum;
- a rib that extends from said first sidewall into said plenum to control expansion of a cooling fluid from said cooling cavity into said plenum, wherein said rib extends radially between opposing sides of said plenum such that said cooling cavity extends along said first sidewall, one of said opposing sides defining a floor and another one of said opposing sides bounded by a wall of said tip, said rib extends transversely between said opposing sides, a portion of said rib extends from said first sidewall and terminates prior to said second sidewall, and said cooling cavity has an outlet into said plenum, said outlet defined along said floor.
A core assembly for fabricating a component, comprising:
- a first core that defines a first cooling cavity of a component;
- a second core that defines a second cooling cavity of said component;
- a partial rib that extends from said first core and said second core and defines a plenum of said component;
- and
- at least one cut-out in said partial rib that defines a rib in said component, wherein said partial rib extends radially between opposing sides of said plenum such that said first cooling cavity and said second cooling cavity extend along a first sidewall of said component on opposed sides of said partial rib, said partial rib extends transversely between said opposing sides, a portion of said partial rib extends from said first sidewall of said component and terminates prior to a second sidewall of said component, said first core and said second core arranged such that said first and second cooling cavities have respective first and second outlets into said plenum, and said first and second outlets both defined along a common one of said opposing sides such that said first and second outlets are spaced apart by said partial rib.
